A preliminary study on the feeding regime of European pilchard (Sardina pilchardus Walbaum 1792) in Izmir Bay, Turkey, Eastern Aegean Sea [PDF]

, 2005
The gut contents of Sardina pilchardus specimens captured in Izmir Bay were examined in order to determine their feeding regimes. Of the 365 stomachs examined, 321 (87.95%) contained food and 44 (12.05%) were empty. Analysis of gut contents verified that

Acoustic Observations Unveil Seasonal Fluctuations and Regulation of Zooplankton Biomass and Its Vertical Distribution at a Mid‐Latitude Long‐Term Ocean Observatory

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Zooplanktonic organisms are considered a key link between different trophic levels. The ecosystem structure and dynamics are affected by changes in their population and phenology. In this work, the causes and timing of changes within the seasonal cycle of zooplankton biomass vertical distribution in oceanic waters of the Bay of Biscay were ...

Under‐Ice Ecological and Biogeochemical Dynamics at the Onset of Spring Thaw in Four Arsenic‐Contaminated Subarctic Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Interactions between aquatic organisms and contaminants in under‐ice lake environments are poorly characterized relative to ice‐free seasons. Here, we compared under‐ice arsenic biogeochemical processes and plankton community composition in four subarctic lakes spanning an arsenic contamination gradient.

Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.
